Definitions

  • the present invention relates in particular to an adapter for connecting a wiper blade to a drive arm, in particular a motor vehicle.
  • a car is conventionally equipped with windshield wipers to wash the windshield and to prevent the driver's vision from being disturbed.
  • These wipers generally comprise a drive arm, performing an angular reciprocating movement, and elongate brushes, themselves carrying scraper blades made of an elastic material. These blades rub against the windshield and evacuate the water by bringing it out of the driver's field of vision.
  • the brooms are made in the form, or, in a conventional version, articulated stirrups that hold the scraper blade in several discrete places by giving it a bend allowing it to marry the eventual curvature of the windshield, or, in a newer version called " flat blade” (for "flat blade”), a semi-rigid assembly that keeps the scraper blade along its length thanks to one or bending vertebrae to apply the broom on the bumper -brise without having to use stirrups.
  • the blade is attached to the drive arm by a connector system including a connector and an adapter.
  • the connector is a piece which is secured to the blade and which is usually attached directly to the scraper blade or the flat broom, while the adapter is secured to the arm.
  • the adapter is an intermediate piece that allows the connection and attachment of the connector on the drive arm. It is generally configured to be engaged in a head or end piece in the form of a clevis and U-shaped cross section of the drive arm.
  • the connector and the adapter each comprise hinge means configured to cooperate with means complementary to the other member, to define at least one transverse pivot axis of the connector vis-à-vis the adapter, which is a swiveling axis of the blade vis-à-vis the arm.
  • one of the members, such as the connector generally comprises a substantially cylindrical physical axis which defines the axis of articulation and which is received in a housing of complementary shape to the other member.
  • the adapter generally comprises a body configured to be engaged in the end piece of the arm so that the body extends at least partially between two substantially parallel lateral legs of the end piece.
  • the body of the adapter is connected at one end to a head, on which the free end of the end piece abuts.
  • the body of the adapter generally comprises an actuating button which is engaged by elastic latching in an orifice of the end piece, when the latter is in abutment on the head, to lock the adapter vis-à- screw the end piece in this position.
  • An adapter allows to associate a broom to a particular type of end piece or arm.
  • end pieces U section for example, there are several varieties. These varieties are very similar in appearance but differ from each other in size and in particular in their lateral widths or dimensions, the width of an end piece being defined by the distance between the lateral legs of the end piece and more precisely by the distance between the external faces of these lateral legs. They also vary by the positions of the orifices intended to cooperate with the push buttons of the adapter.
  • the adapter can accidentally disassemble the connector due to a game at the axis of articulation of the adapter vis-à-vis the connector.
  • the invention proposes an improvement to the prior art.
  • the invention proposes for this purpose an adapter for connecting a wiper blade to a drive arm, the adapter comprising two longitudinal side walls spaced from each other so as to form between them at least one configured housing for at least partly receiving a connector of the wiper blade, at least one of the side walls comprising at least one orifice, said side wall further comprising a bearing means projecting from an outer face of the side wall , characterized in that the support means is traversed by at least one orifice, said support means being derived material with the outer face of the side wall.
  • the adapter according to the invention can be used as universal adapter, as will be described in detail in the following, that is to say an adapter for at least two different drive arms, such as for example at minus one end arm or U-shaped end piece, at least one stem arm (generally without end piece), at least one side-lock arm, etc.
  • the adapter according to the invention overcomes the problem of the prior art of accidental disassembly of the adapter.
  • the projecting projection means allow a better maintenance, in particular lateral or transverse, of the adapter on the connector. They are configured to cooperate by support with complementary means of another element to prevent or limit deformation of the adapter. They can also be configured to stiffen the side walls of the adapter and reduce their flexibility.
  • the invention also covers a first assembly comprising an adapter according to any one of the features presented above and a connector integral with the wiper blade.
  • the invention also relates to a second assembly comprising an adapter as above and said connecting rod arm member which is configured to cover at least part of said adapter, wherein said connecting member comprises two longitudinal side walls for s extend substantially parallel to the side walls of the adapter, and having on their inner faces projecting means which are configured to abut in the transverse direction on the support means of the side walls of the adapter.
  • the invention covers a wiper blade or drive arm, characterized in that it comprises or carries a adapter according to one of the features listed above, or a first or second set as evoked also.
  • the invention covers a third assembly comprising a drive arm and an adapter as presented above, or a first and / or second assembly shown above, the drive arm comprising a transverse pin received in at least one adapter ports, and an L-shaped latch extending transversely along the spindle.
  • the longitudinal or lateral names refer to the orientation of the wiper blade or the drive arm according to the invention.
  • the longitudinal direction corresponds to the main axis of the wiper blade or the arm in which it extends
  • the lateral orientations correspond to intersecting lines, that is to say which cross the longitudinal direction, in particular perpendicular to the longitudinal axis of the wiper blade or the arm in its plane of rotation.

  • the body 16 of the wiper blade 12 may include an upper aerodynamic deflector 20 for improving the operation of the wiper system, the purpose of this deflector being to improve the wiper blade plating on the windshield and therefore the aerodynamic performance of the windshield wiper.
  • the wiper blade 12 may further comprise end tips 22 or hooking staples of the blade 18 and the vertebra on the body 16, these ends 22 being located at each of the longitudinal ends of the body 16.

Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention concerne notamment un adaptateur pour relier un balai d'essuyage à un bras d'entraînement, en particulier de véhicule automobile.The present invention relates in particular to an adapter for connecting a wiper blade to a drive arm, in particular a motor vehicle.

ETAT DE L'ARTSTATE OF THE ART

Une automobile est classiquement équipée d'essuie-glaces pour assurer un lavage du pare-brise et éviter que la vision qu'a le conducteur de son environnement ne soit perturbée. Ces essuie-glaces comprennent en général un bras d'entrainement, effectuant un mouvement de va-et-vient angulaire, et des balais allongés, porteurs eux-mêmes de lames racleuses réalisées en une matière élastique. Ces lames frottent contre le pare-brise et évacuent l'eau en l'amenant en dehors du champ de vision du conducteur. Les balais sont réalisés sous la forme, soit, dans une version classique, d'étriers articulés qui tiennent la lame racleuse en plusieurs endroits discrets en lui conférant un cintrage lui permettant d'épouser l'éventuelle courbure du pare-brise, soit, dans une version plus récente dénommée "flat blade" (pour "lame plate"), d'un ensemble semi-rigide qui maintient la lame racleuse sur toute sa longueur grâce à une ou des vertèbres de cintrage permettant d'appliquer le balai sur le pare-brise sans avoir à utiliser d'étriers.A car is conventionally equipped with windshield wipers to wash the windshield and to prevent the driver's vision from being disturbed. These wipers generally comprise a drive arm, performing an angular reciprocating movement, and elongate brushes, themselves carrying scraper blades made of an elastic material. These blades rub against the windshield and evacuate the water by bringing it out of the driver's field of vision. The brooms are made in the form, or, in a conventional version, articulated stirrups that hold the scraper blade in several discrete places by giving it a bend allowing it to marry the eventual curvature of the windshield, or, in a newer version called " flat blade" (for "flat blade"), a semi-rigid assembly that keeps the scraper blade along its length thanks to one or bending vertebrae to apply the broom on the bumper -brise without having to use stirrups.

Le balai est rattaché au bras d'entraînement par un système de connexion comportant un connecteur et un adaptateur. Le connecteur est une pièce qui est solidarisée au balai et qui est en général fixée directement sur la lame racleuse ou sur le balai plat, alors que l'adaptateur est solidaire du bras. L'adaptateur est une pièce intermédiaire qui permet la liaison et la fixation du connecteur sur le bras d'entraînement. Il est en général configuré pour être engagé dans une tête ou pièce terminale en forme de chape et à section transversale en U du bras d'entraînement.The blade is attached to the drive arm by a connector system including a connector and an adapter. The connector is a piece which is secured to the blade and which is usually attached directly to the scraper blade or the flat broom, while the adapter is secured to the arm. The adapter is an intermediate piece that allows the connection and attachment of the connector on the drive arm. It is generally configured to be engaged in a head or end piece in the form of a clevis and U-shaped cross section of the drive arm.

Le connecteur et l'adaptateur comprennent chacun des moyens d'articulation configurés pour coopérer avec des moyens complémentaires de l'autre organe, pour définir au moins un axe transversal de pivotement du connecteur vis-à-vis de l'adaptateur, qui est un axe de pivotement du balai vis-à-vis du bras. Dans la technique actuelle, l'un des organes, tels que le connecteur, comprend en général un axe physique sensiblement cylindrique qui définit l'axe d'articulation et qui est reçu dans un logement de forme complémentaire de l'autre organe.The connector and the adapter each comprise hinge means configured to cooperate with means complementary to the other member, to define at least one transverse pivot axis of the connector vis-à-vis the adapter, which is a swiveling axis of the blade vis-à-vis the arm. In the present art, one of the members, such as the connector, generally comprises a substantially cylindrical physical axis which defines the axis of articulation and which is received in a housing of complementary shape to the other member.

L'adaptateur comporte en général un corps configuré pour être engagé dans la pièce terminale du bras de façon à ce que ce corps s'étende au moins en partie entre deux jambes latérales sensiblement parallèles de la pièce terminale. Le corps de l'adaptateur est relié à une extrémité à une tête, sur laquelle l'extrémité libre de la pièce terminale vient en butée. Enfin, le corps de l'adaptateur comprend en général un bouton d'actionnement qui est engagé par encliquetage élastique dans un orifice de la pièce terminale, lorsque cette dernière est en butée sur la tête, afin de verrouiller l'adaptateur vis-à-vis de la pièce terminale dans cette position.The adapter generally comprises a body configured to be engaged in the end piece of the arm so that the body extends at least partially between two substantially parallel lateral legs of the end piece. The body of the adapter is connected at one end to a head, on which the free end of the end piece abuts. Finally, the body of the adapter generally comprises an actuating button which is engaged by elastic latching in an orifice of the end piece, when the latter is in abutment on the head, to lock the adapter vis-à- screw the end piece in this position.

Un adaptateur permet d'associer un balai à un type particulier de pièce terminale ou de bras. Dans le cas des pièces terminales précitées à section en U par exemple, il en existe plusieurs variétés. Ces variétés sont très proches en apparence mais diffèrent les unes des autres par des dimensions et en particulier par leurs largeurs ou dimensions latérales, la largeur d'une pièce terminale étant définie par la distance entre les jambes latérales de la pièce terminale et plus exactement par la distance entre les faces externes de ces jambes latérales. Elles varient également par les positions des orifices destinés à coopérer avec les boutons poussoirs de l'adaptateur.An adapter allows to associate a broom to a particular type of end piece or arm. In the case of the aforementioned end pieces U section for example, there are several varieties. These varieties are very similar in appearance but differ from each other in size and in particular in their lateral widths or dimensions, the width of an end piece being defined by the distance between the lateral legs of the end piece and more precisely by the distance between the external faces of these lateral legs. They also vary by the positions of the orifices intended to cooperate with the push buttons of the adapter.

Dans la technique actuelle, il existe autant de variétés d'adaptateur que de variétés de pièces terminales ou d'extrémités de bras d'entrainement, ce qui n'est pas pratique ni économique. Il existe donc un réel besoin d'un adaptateur universel apte à être monté sur au moins deux, voire plus, pièces terminales de bras d'essuie-glace.In the present art, there are as many varieties of adapter as varieties of end pieces or ends of drive arms, which is impractical or economical. There is therefore a Real need for a universal adapter adapted to be mounted on at least two or more end pieces of wiper arm.

Par ailleurs, on a constaté qu'en fonctionnement, l'adaptateur peut se désassembler accidentellement du connecteur du fait d'un jeu au niveau de l'axe d'articulation de l'adaptateur vis-à-vis du connecteur.Furthermore, it has been found that in operation, the adapter can accidentally disassemble the connector due to a game at the axis of articulation of the adapter vis-à-vis the connector.

L'invention propose un perfectionnement à la technique antérieure.The invention proposes an improvement to the prior art.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

Il faut noter que les figures exposent l'invention de manière détaillée pour mettre en oeuvre l'invention, lesdites figures pouvant bien entendu servir à mieux définir l'invention le cas échéant.It should be noted that the figures disclose the invention in detail to implement the invention, said figures can of course be used to better define the invention where appropriate.

Dans la description qui suit, les dénominations longitudinales ou latérales se réfèrent à l'orientation du balai d'essuyage ou du bras d'entraînement selon l'invention. La direction longitudinale correspond à l'axe principal du balai d'essuyage ou du bras dans lequel il s'étend, alors que les orientations latérales correspondent à des droites concourantes, c'est-à-dire qui croisent la direction longitudinale, notamment perpendiculaires à l'axe longitudinal du balai d'essuyage ou du bras dans son plan de rotation. Pour les directions longitudinales, les dénominations extérieure (ou avant) ou intérieure (ou arrière) s'apprécient par rapport au point de fixation du balai d'essuyage sur le bras, la dénomination intérieure correspondant à la partie où le bras et un demi-balai s'étendent, ou par rapport au point de fixation du bras au véhicule. Enfin, les directions référencées comme supérieures ou inférieures correspondent à des orientations perpendiculaires au plan de rotation du balai d'essuyage, la dénomination inférieure contenant le plan du pare-brise.In the following description, the longitudinal or lateral names refer to the orientation of the wiper blade or the drive arm according to the invention. The longitudinal direction corresponds to the main axis of the wiper blade or the arm in which it extends, while the lateral orientations correspond to intersecting lines, that is to say which cross the longitudinal direction, in particular perpendicular to the longitudinal axis of the wiper blade or the arm in its plane of rotation. For the longitudinal directions, the names outside (or front) or inside (or back) are appreciated relative to the point of attachment of the wiper blade on the arm, the inner name corresponding to the part where the arm and a half broom extend, or relative to the attachment point of the arm to the vehicle. Finally, the directions referenced as higher or lower correspond to orientations perpendicular to the plane of rotation of the wiper blade, the lower denomination containing the plane of the windshield.

Il est illustré à la figure 1 un essuie-glace 10 comportant notamment un balai d'essuyage 12 et un bras 14 d'entraînement du balai d'essuyage 12. Le bras d'entraînement forme un bras d'essuie-glace.It is illustrated at figure 1 a wiper 10 including a wiper blade 12 and a drive arm 14 of the wiper blade 12. The drive arm forms a wiper arm.

Le balai d'essuyage 12 est de préférence du type flat blade et comprend un corps longitudinal 16, une lame d'essuyage 18, en général en caoutchouc, et au moins une vertèbre qui rigidifie la lame et favorise son application sur un pare-brise de véhicule.The wiper blade 12 is preferably of the flat blade type and comprises a longitudinal body 16, a wiper blade 18, generally of rubber, and at least one vertebra which stiffens the blade and promotes its application on a windshield of vehicle.

Le corps 16 du balai d'essuyage 12 peut comporter un déflecteur aérodynamique supérieur 20 destiné à améliorer le fonctionnement du système d'essuyage, le but de ce déflecteur étant d'améliorer le plaquage du balai d'essuyage sur le pare-brise et donc la performance aérodynamique de l'essuie-glace.The body 16 of the wiper blade 12 may include an upper aerodynamic deflector 20 for improving the operation of the wiper system, the purpose of this deflector being to improve the wiper blade plating on the windshield and therefore the aerodynamic performance of the windshield wiper.

Le balai d'essuyage 12 peut comprendre en outre des embouts d'extrémité 22 ou agrafes d'accrochage de la lame 18 et de la vertèbre sur le corps 16, ces embouts 22 étant situés à chacune des extrémités longitudinales du corps 16.The wiper blade 12 may further comprise end tips 22 or hooking staples of the blade 18 and the vertebra on the body 16, these ends 22 being located at each of the longitudinal ends of the body 16.

Le balai d'essuyage 12 comprend sensiblement en son milieu un connecteur 24 intermédiaire. Un adaptateur 26 solidaire du bras 14 est monté sur le connecteur 24 de façon à garder un degré de liberté en pivotement autour d'un axe d'articulation ou de pivotement Y qui est un axe transversal sensiblement perpendiculaire à l'axe longitudinal du balai d'essuyage 12. Ce degré de liberté autorise un pivotement du balai d'essuyage 12 vis-à-vis du bras 14 et permet ainsi au balai d'essuyage de suivre la courbure du pare-brise lors de ses déplacements. L'adaptateur 26 peut être désolidarisé du bras 14 par appui sur un bouton d'actionnement, ici un bouton poussoir 27, porté par l'adaptateur.The wiper blade 12 comprises substantially in its middle an intermediate connector 24. An adapter 26 secured to the arm 14 is mounted on the connector 24 so as to maintain a degree of freedom in pivoting about an axis of articulation or pivoting Y which is a transverse axis substantially perpendicular to the longitudinal axis of the broom. 12. This degree of freedom allows pivoting of the wiper blade 12 vis-à-vis the arm 14 and thus allows the wiper blade to follow the curvature of the windshield during its movements. The adapter 26 can be detached from the arm 14 by pressing an actuation button, here a push button 27, carried by the adapter.

Le bras 14 est destiné à être entraîné par un moteur pour suivre un mouvement angulaire de va-et-vient permettant d'évacuer l'eau et éventuellement d'autres éléments indésirables recouvrant le pare-brise. L'adaptateur 26 assure la liaison du balai d'essuyage 12 au bras 14 et en particulier à une tête ou pièce terminale 28 du bras qui peut être formée d'une seule pièce avec le bras ou rapportée et fixée sur celui-ci.The arm 14 is intended to be driven by a motor to follow a reciprocating angular movement to evacuate the water and possibly other undesirable elements covering the windshield. The adapter 26 connects the wiper blade 12 to the arm 14 and in particular to a head or end piece 28 of the arm which can be formed integrally with the arm or attached and fixed thereto.

Dans l'exemple représenté, la pièce terminale 28 du bras forme une chape à section transversale sensiblement en U.In the example shown, the end piece 28 of the arm forms a yoke with a substantially U-shaped cross-section.

La pièce terminale 28 a une forme allongée dont l'axe d'allongement A est en général sensiblement parallèle à l'axe d'allongement ou longitudinal du balai d'essuyage 12. Il s'agit de la direction longitudinale de l'adaptateur. La pièce terminale 28 comprend une partie 30 de liaison au reste du bras 14, par exemple par sertissage. Cette partie 30 a une forme générale allongée et s'étend le long d'un axe B sensiblement parallèle à l'axe longitudinal A et à distance de cet axe, comme cela est visible aux figures 1 et 2. La partie 30 est reliée à une extrémité arrière ou intérieure de du reste de la pièce terminale 28.The end piece 28 has an elongate shape whose elongation axis A is generally substantially parallel to the axis of elongation or longitudinal wiper blade 12. This is the longitudinal direction of the adapter. The end piece 28 comprises a connecting portion 30 to the rest of the arm 14, for example by crimping. This portion 30 has a generally elongate shape and extends along an axis B substantially parallel to the longitudinal axis A and at a distance from this axis, as can be seen at Figures 1 and 2 . The portion 30 is connected to a rear or inner end of the remainder of the end piece 28.

L'adaptateur 26 est du type « universel » et est destiné à être monté indifféremment sur des pièces terminales 28 de différents bras, voire sur des bras non équipés de pièces terminales, comme cela sera décrit plus en détail dans ce qui suit en référence aux figures 10 à 20.The adapter 26 is of the "universal" type and is intended to be mounted indifferently on end pieces 28 of different arms, or even on arms not equipped with end pieces, as will be described in greater detail in the following with reference to the Figures 10 to 20 .

Les figures 2 à 9 montrent un mode de réalisation de l'adaptateur 26 selon l'invention ainsi que du connecteur 24 destiné à coopérer avec cet adaptateur, l'adaptateur et le connecteur formant ensemble un système de connexion du balai d'essuyage 12 au bras 14 ou à un bras 14 parmi plusieurs types de bras.The Figures 2 to 9 show an embodiment of the adapter 26 according to the invention as well as the connector 24 intended to cooperate with this adapter, the adapter and the connector together forming a connection system of the wiper blade 12 to the arm 14 or a arm 14 among several types of arms.

L'adaptateur 24 a une forme générale allongée le long de l'axe longitudinal A, autrement appelé direction longitudinale. Il comprend un corps comportant deux parois latérales 42a, 42b par exemple sensiblement parallèles entre elles et à l'axe longitudinal A, et à distance l'une de l'autre. Ces parois 42a, 42b sont reliées entre elles à leurs extrémités supérieures par une paroi transversale supérieure 44 sensiblement perpendiculaire aux parois latérales 42a, 42b. Les parois 42a, 42b, 44 ont ici une forme allongée en direction longitudinale.The adapter 24 is generally elongated along the longitudinal axis A, otherwise known as the longitudinal direction. It comprises a body having two lateral walls 42a, 42b for example substantially parallel to each other and to the longitudinal axis A, and at a distance from one another. These walls 42a, 42b are interconnected at their upper ends by an upper transverse wall 44 substantially perpendicular to the side walls 42a, 42b. The walls 42a, 42b, 44 here have an elongated shape in the longitudinal direction.

Ces parois latérales 42a et 42b sont toutes deux délimitées par une face interne tournée vers un logement 45 et par une face externe référencée 75. Cette face externe 75 est bordée par un bord longitudinal inférieur 77 et par un bord longitudinal supérieur 79 opposé au bord longitudinal inférieur 77.These side walls 42a and 42b are both delimited by an internal face turned towards a housing 45 and an external face referenced 75. This outer face 75 is bordered by a lower longitudinal edge 77 and an upper longitudinal edge 79 opposite the longitudinal edge. lower 77.

Les parois 42a, 42b, 44 de l'adaptateur 26 définissent entre elles un espace longitudinal, autrement appelé logement, 45 dans lequel est destinée à être montée une partie du connecteur 24. Les parois 42a, 42b sont ici du type à double peau et comportent chacune deux peaux, respectivement interne et externe, parallèles et à distance transversale l'une de l'autre. Les peaux sont reliées ensemble par des nervures rectilignes transversales.The walls 42a, 42b, 44 of the adapter 26 define between them a longitudinal space, otherwise called housing, 45 in which is intended to be mounted a portion of the connector 24. The walls 42a, 42b are here of the double skin type and each comprise two skins, respectively internal and external, parallel and at a distance transverse to one another. The skins are connected together by transverse rectilinear ribs.

Le corps de l'adaptateur 26 est relié à une première de ses extrémités longitudinales à un carénage ou capotage, aussi appelé casquette ou tête 46. Cette tête 46 a une dimension latérale supérieure à celle du corps de l'adaptateur et une hauteur également supérieure à celle du corps. Les parois latérales 42a, 42b du corps de l'adaptateur sont ainsi en retrait ou décalées par rapport à des faces latérales externes 46a de la tête, et sa paroi supérieure 44 est en retrait ou décalée par rapport à une face supérieure externe 46b de la tête.The body of the adapter 26 is connected at a first of its longitudinal ends to a fairing or cowling, also called cap or head 46. This head 46 has a lateral dimension greater than that of the body of the adapter and a height also greater than that of the body. The lateral walls 42a, 42b of the body of the adapter are thus recessed or offset relative to external lateral faces 46a of the head, and its upper wall 44 is set back or offset with respect to an external upper face 46b of the head.

Les faces latérales 46a de la tête 46 sont reliées aux parois latérales 42a, 42b du corps par des faces arrière latérales 48a, respectivement, qui s'étendent sensiblement perpendiculairement à l'axe longitudinal A. La face supérieure 46c de la casquette 46 est reliée à la paroi supérieure 44 du corps par une autre face arrière supérieure 48b qui s'étend également sensiblement perpendiculairement à l'axe longitudinal A.The lateral faces 46a of the head 46 are connected to the lateral walls 42a, 42b of the body by lateral rear faces 48a, respectively, which extend substantially perpendicularly to the longitudinal axis A. The upper face 46c of the cap 46 is connected at the upper wall 44 of the body by another upper rear face 48b which also extends substantially perpendicular to the longitudinal axis A.

Les faces arrière 48a, 48b de la tête 46 forment des faces d'appui de l'extrémité extérieure ou avant de la pièce terminale 28. Plus précisément, en position montée de l'adaptateur dans la pièce terminale 28, les bords libres avant des jambes latérales de la pièce terminale sont destinés à venir en appui sur les faces 48a, et le bord libre avant de la paroi transversale de la pièce terminale est destiné à venir en appui sur la face 48b.The rear faces 48a, 48b of the head 46 form bearing faces of the outer end or front of the end piece 28. More precisely, in the mounted position of the adapter in the end piece 28, the free edges before the lateral legs of the end piece are intended to bear on the faces 48a, and the free edge before the transverse wall of the end piece is intended to bear on the face 48b.

La paroi supérieure 44 du corps de l'adaptateur 26 comprend, sensiblement en son milieu, une fenêtre 49. La paroi supérieure 44 comprend à son extrémité longitudinale opposée à la tête 46 des fentes longitudinales parallèles entre elles et à l'axe longitudinal A et espacées les unes des autres, de façon à définir entre elles au moins une portion d'une languette longitudinale 50.The upper wall 44 of the body of the adapter 26 comprises, substantially in the middle, a window 49. The upper wall 44 comprises at its longitudinal end opposite the head 46 longitudinal slots parallel to each other and to the longitudinal axis A and spaced from each other, so as to define between them at least a portion of a longitudinal tongue 50.

La languette 50 s'étend longitudinalement du côté opposé à la tête 46, dans le prolongement de la paroi supérieure 44. Elle est élastiquement déformable et est reliée à son extrémité libre extérieure ou avant au bouton poussoir supérieur 27 précité, qui est en saillie sur la languette 50. A l'état libre sans contrainte, chaque languette 50 est telle que le bouton poussoir 27 est situé au-dessus d'un plan passant par la paroi supérieure 44. Les déformations élastiques des languettes ont ici lieu dans un plan longitudinal médian sensiblement vertical, c'est-à-dire sensiblement perpendiculaire à la paroi supérieure 44. L'adaptateur 26 est ainsi équipé d'un bouton poussoir supérieur 27.The tongue 50 extends longitudinally on the opposite side to the head 46, in the extension of the upper wall 44. It is elastically deformable and is connected to its outer free end or front to the aforementioned upper push button 27, which projects from the tongue 50. In the free state without constraint, each tongue 50 is such that the push button 27 is located above a plane passing through the upper wall 44. The elastic deformations of the tongues here take place in a longitudinal plane median substantially vertical, that is to say substantially perpendicular to the upper wall 44. The adapter 26 is thus equipped with an upper push button 27.

Lors du montage de l'adaptateur 26 dans la pièce terminale 28, le bouton poussoir 27 est destiné à s'engager par encliquetage élastique dans l'ouverture 38 pour verrouiller l'adaptateur vis-à-vis de la pièce terminale.When mounting the adapter 26 in the end piece 28, the push button 27 is intended to engage resiliently snap into the opening 38 to lock the adapter vis-à-vis the end piece.

L'adaptateur 26 comprend en outre un orifice supérieur 51 d'engagement d'une patte d'une pièce terminale de bras. Cet orifice 51 est ici formé en partie dans la tête 46, à l'extrémité arrière de celle-ci, et en partie dans la paroi supérieure 44, à l'extrémité avant de celle-ci. L'orifice 51 a une forme générale carrée ou rectangulaire.The adapter 26 further comprises an upper orifice 51 for engaging a tab of an end piece of arm. This orifice 51 is here formed partly in the head 46, at the rear end thereof, and partly in the upper wall 44, at the front end thereof. The orifice 51 has a generally square or rectangular shape.

Les parois latérales 42a, 42b du corps se prolongent longitudinalement vers l'intérieur par des pattes longitudinales 52a, 52b élastiquement déformables. Chaque paroi 42a, 42b est reliée à une patte 52a, 52b, ces pattes 52a, 52b étant sensiblement parallèles et symétriques par rapport à un plan longitudinal médian, sensiblement vertical, c'est-à-dire perpendiculaire à la paroi supérieure 44 de l'adaptateur. Les extrémités libres des pattes 52a, 52b, qui sont situées du côté opposé à la tête 46, portent chacune un bouton poussoir latéral 27' en saillie. Chaque patte 52a, 52b porte ainsi un bouton poussoir 27". Les déformations élastiques des pattes 52a, 52b ont ici lieu dans un plan longitudinal sensiblement horizontal, c'est-à-dire sensiblement parallèle à la paroi supérieure 44. Les pattes 52a, 52b peuvent être rapprochées l'une de l'autre par déformation élastique. Les boutons poussoirs 27" sont conformés pour coopérer avec des encoches de la pièce terminale 28, comme cela sera décrit plus en détail dans ce qui suit.The lateral walls 42a, 42b of the body extend longitudinally inwardly by longitudinal tabs 52a, 52b that are elastically deformable. Each wall 42a, 42b is connected to a tab 52a, 52b, these tabs 52a, 52b being substantially parallel and symmetrical with respect to a median longitudinal plane, substantially vertical, that is to say perpendicular to the upper wall 44 of the 'adapter. The free ends of the tabs 52a, 52b, which are located on the opposite side to the head 46, each carry a lateral push button 27 'projecting. Each tab 52a, 52b thus carries a push button 27. The elastic deformations of the tabs 52a, 52b here take place in a substantially horizontal longitudinal plane, that is to say substantially parallel to the upper wall 44. The tabs 52a, 52b can be brought closer to each other by elastic deformation The push buttons 27 "are shaped to cooperate with notches of the end piece 28, as will be described in more detail in the following.

Les parois latérales 42a, 42b comprennent chacune un orifice 56 traversant. Les orifices 56 des parois latérales 42a, 42b sont sensiblement coaxiaux et définissent ici l'axe Y de pivotement de l'adaptateur 24 sur le connecteur 24, et donc du balai d'essuyage vis-à-vis du bras. Les orifices 56 sont par exemple à section circulaire et comprennent chacun une surface interne 56a sensiblement cylindrique. Les orifices 56 débouchent à leurs extrémités latérales externes sur les faces externes 75 des parois 42a, 42b, respectivement, et à leurs extrémités latérales internes dans le logement 45.The side walls 42a, 42b each comprise a through orifice 56. The orifices 56 of the side walls 42a, 42b are substantially coaxial and here define the axis Y of pivoting of the adapter 24 on the connector 24, and thus of the wiper blade vis-à-vis the arm. The orifices 56 are for example circular in section and each comprise a substantially cylindrical inner surface 56a. The orifices 56 open at their outer lateral ends on the outer faces 75 of the walls 42a, 42b, respectively, and at their inner lateral ends in the housing 45.

Les faces latérales internes en regard des parois latérales 42a, 42b comprennent des protubérances 60. Chaque paroi latérale 42a, 42b comprend une protubérance 60, les protubérances étant ici en regard l'une de l'autre et s'étendant sensiblement l'une vers l'autre. Les protubérances 60 sont symétriques par rapport à un plan longitudinal médian de l'adaptateur, perpendiculaire à la paroi supérieure 44. Chaque protubérance 60 présente également un plan de symétrie passant par l'axe de pivotement Y et perpendiculaire à l'axe longiA.The internal lateral faces facing the lateral walls 42a, 42b comprise protuberances 60. Each lateral wall 42a, 42b comprises a protuberance 60, the protuberances being here facing one another and extending substantially one towards the other. the other. The protuberances 60 are symmetrical with respect to a median longitudinal plane of the adapter, perpendicular to the upper wall 44. Each protuberance 60 also has a plane of symmetry passing through the pivot axis Y and perpendicular to the long axis.

Chaque protubérance 60 est trouée et comprend un trou traversant. Ce trou est ici formé par un des orifices 56 précités. Chaque protubérance 60 est ainsi située sur la face interne de la paroi latérale 42a ou 42b de sorte à être traversée par l'orifice 56 de cette paroi.Each protuberance 60 is perforated and comprises a through hole. This hole is here formed by one of the aforementioned orifices 56. Each protuberance 60 is thus located on the inner face of the side wall 42a or 42b so as to be traversed by the orifice 56 of this wall.

Chaque protubérance 60 a une forme générale cylindrique et ici tubulaire du fait de l'orifice 56 qui la traverse. L'axe de chaque orifice 56, qui est confondu avec l'axe de pivotement Y, est également confondu avec l'axe de la protubérance cylindrique 60 correspondante, si bien que l'orifice est centré vis-à-vis de la protubérance. Chaque protubérance 60 forme ainsi un bourrelet annulaire de matière autour de l'orifice 56, ayant sensiblement une épaisseur radiale par rapport à l'axe de pivotement Y sensiblement constante. Chaque protubérance 60 a une dimension axiale le long de l'axe de pivotement Y qui représente environ 10 à 20% de la dimension axiale ou largeur du logement 45 le long de l'axe de pivotement Y. Chaque protubérance 60 a un diamètre externe qui représente environ 60 à 80% de la hauteur de la paroi latérale 42a, 42b correspondante, mesurée dans une direction sensiblement perpendiculaire à l'axe de pivotement Y.Each protuberance 60 has a generally cylindrical shape and here tubular due to the orifice 56 which passes through it. The axis of each orifice 56, which coincides with the pivot axis Y, is also coincident with the axis of the corresponding cylindrical protuberance 60, so that the orifice is centered with respect to the protuberance. Each protuberance 60 thus forms an annular bead of material around the orifice 56, having substantially a radial thickness relative to the pivot axis Y substantially constant. Each protrusion 60 has an axial dimension along the pivot axis Y which represents about 10 to 20% of the axial dimension or width of the housing 45 along the pivot axis Y. Each protrusion 60 has an outer diameter which is about 60 to 80% of the height of the corresponding side wall 42a, 42b, measured in a direction substantially perpendicular to the pivot axis Y.

Comme cela est visible aux figures 5 et 6, chaque protubérance 60 comprend une partie, ici inférieure, tronquée ou chanfreinée. Chaque partie tronquée ou chanfreinée définit une rampe 62 qui s'étend dans un plan incliné par rapport aux parois latérales 42a, 42b. Chaque rampe 62 définit une surface de glissement destinée à coopérer avec le connecteur 24. Les rampes 62 des protubérances 60 sont inclinées de sorte qu'elles s'éloignent l'une de l'autre du haut vers le bas. Leurs extrémité inférieures, situées du côté opposé à la paroi supérieure 44, sont espacées l'une de l'autre d'une distance L le long de l'axe de pivotement Y (figure 6). L'extrémité inférieure de chaque rampe 60 s'étend à faible distance, le long de l'axe de pivotement Y, de la face interne de la paroi latérale 42a, 42b correspondante et peut être directement reliée à cette face interne. Dans ce dernier cas, la distance L est sensiblement égale à la distance entre les faces internes des parois 42a, 42b ou à la largeur du logement 45. Chaque rampe 62 s'étend sur une circonférence autour de l'axe de pivotement Y, représentant un angle compris entre 30 et 150°, et de préférence entre 90 et 120°.As can be seen in figures 5 and 6 each protrusion 60 comprises a portion, here below, truncated or chamfered. Each truncated or chamfered portion defines a ramp 62 which extends in a plane inclined relative to the side walls 42a, 42b. Each ramp 62 defines a sliding surface intended to cooperate with the connector 24. The ramps 62 of the protuberances 60 are inclined so that they move away from each other from top to bottom. Their lower ends, located on the side opposite to the upper wall 44, are spaced from each other by a distance L along the pivot axis Y ( figure 6 ). The lower end of each ramp 60 extends at a short distance, along the pivot axis Y, of the inner face of the corresponding side wall 42a, 42b and can be directly connected to this inner face. In the latter case, the distance L is substantially equal to the distance between the internal faces of the walls 42a, 42b or the width of the housing 45. Each ramp 62 extends over a circumference around the pivot axis Y, representing an angle of between 30 and 150 °, and preferably between 90 and 120 °.

Les parois latérales 42a, 42b du corps de l'adaptateur 26 comprennent en outre sur leurs faces externes 75 un ou des moyens d'appui 54, 54a en saillie de la face externe 75 qui les porte. Ce moyen d'appui 54, 54a définit des faces d'appui en direction transversale, c'est-à-dire perpendiculairement à la direction longitudinale A passant par les faces latérales 42a et 42b.The side walls 42a, 42b of the body of the adapter 26 further comprise on their outer faces 75 or one of the support means 54, 54a projecting from the outer face 75 which carries them. This support means 54, 54a defines bearing faces in the transverse direction, that is to say perpendicularly to the longitudinal direction A passing through the lateral faces 42a and 42b.

Au moins certains 54a de ces moyens d'appui en saillie sont situés au niveau des orifices 56, et sont traversés par ces orifices 56. Il existe ainsi une interférence géométrique entre le périmètre externe de l'orifice 56 et le moyen d'appui 54a.At least some of these protruding support means 54a are located at the orifices 56, and are traversed by these orifices 56. There is thus a geometrical interference between the external perimeter of the orifice 56 and the support means 54a. .

Les moyens d'appui 54, 54a en saillie comprennent ici des bandes de matière 54, 54a en saillie sur les faces externes 75 des parois latérales 42a, 42b. Les bandes de matière ont une forme allongée et s'étendent transversalement à la direction longitudinale A entre les bords longitudinaux inférieurs 77 et supérieurs 79 des parois latérales 42a, 42b, le bord longitudinal supérieur étant commun à la paroi supérieure 44.The bearing means 54, 54a projecting here comprise strips of material 54, 54a projecting on the outer faces 75 of the side walls 42a, 42b. The strips of material have an elongated shape and extend transversely to the longitudinal direction A between the longitudinal edges lower 77 and upper 79 side walls 42a, 42b, the upper longitudinal edge being common to the upper wall 44.

Les bandes de matière 54, 54a définissent des faces d'appui parallèles, ou sensiblement parallèles, entre elles. Ces faces d'appui sont également ici parallèles, ou sensiblement parallèles, aux faces externes 75 des parois latérales 42a, 42b. Un plan passant par la face d'appui d'une ou plusieurs bandes de matières est ainsi parallèle à un plan passant par la face externe 75. Une droite passant par ces faces d'appui est aussi parallèle, ou sensiblement parallèle, à l'axe longitudinal A de l'adaptateur 26.The strips of material 54, 54a define parallel bearing faces, or substantially parallel, between them. These bearing faces are also here parallel, or substantially parallel, to the outer faces 75 of the side walls 42a, 42b. A plane passing through the bearing face of one or more strips of materials is thus parallel to a plane passing through the outer face 75. A line passing through these bearing faces is also parallel, or substantially parallel, to the longitudinal axis A of the adapter 26.

Les bandes de matière 54, 54a sont espacées en direction longitudinale A les unes des autres et réparties sur les parois latérales 42a, 42b dans la même direction. Dans l'exemple représenté, chaque paroi latérale comprend quatre desdites bandes de matière 54, 54a. Les bandes de matière de l'une des parois latérales sont symétriques par rapport aux bandes de matière de l'autre des parois latérales, par rapport à un plan longitudinal médian de l'adaptateur sensiblement perpendiculaire à sa paroi supérieure 44.The material strips 54, 54a are spaced longitudinally A from each other and distributed on the side walls 42a, 42b in the same direction. In the example shown, each side wall comprises four of said strips of material 54, 54a. The strips of material of one of the side walls are symmetrical with respect to the strips of material of the other of the side walls, with respect to a median longitudinal plane of the adapter substantially perpendicular to its upper wall 44.

Les bandes de matière 54, 54a ont sensiblement toutes la même épaisseur mesurée selon l'axe de pivotement Y ou dimension en direction transversale. Les bandes de matière 54a traversées par les orifices 56 ont une largeur ou dimension en direction longitudinale, mesurée selon la direction longitudinale A, inférieure à celle des autres bandes de matière 54, et par exemple également inférieure au diamètre desdits orifices 56.The strips of material 54, 54a have substantially all the same thickness measured along the axis of pivoting Y or dimension in the transverse direction. The strips of material 54a traversed by the orifices 56 have a width or dimension in the longitudinal direction, measured along the longitudinal direction A, smaller than that of the other strips of material 54, and for example also smaller than the diameter of said orifices 56.

Le plan transversal médian perpendiculaire à la paroi supérieure 44 de l'adaptateur 26 et passant par l'axe de pivotement Y traverse les bandes de matière 54a sensiblement en leur milieu et peut par exemple former un plan de symétrie de ces bandes. Autrement dit, les bandes de matière 54a sont notamment sensiblement centrées sur l'axe de pivotement Y et les orifices 56.The median transverse plane perpendicular to the upper wall 44 of the adapter 26 and passing through the pivot axis Y passes through the material strips 54a substantially in their middle and may for example form a plane of symmetry of these bands. In other words, the material strips 54a are in particular substantially centered on the pivot axis Y and the orifices 56.

L'adaptateur 26 décrit ci-dessus est avantageusement unitaire, c'est-à-dire constitué par une même matière synthétique. Il peut ainsi être fabriqué au cours d'une unique opération de moulage, notamment par injection.The adapter 26 described above is advantageously unitary, that is to say constituted by the same synthetic material. It can thus be manufactured during a single molding operation, in particular by injection.

L'adaptateur 26 est fixé au connecteur 24 grâce aux protubérances 60 qui forment des moyens de fixation de l'adaptateur au connecteur et qui peuvent en outre former des moyens de pivotement de l'adaptateur vis-à-vis du connecteur. Les moyens de fixation sont du type à encliquetage élastique, les protubérances 60 de l'adaptateur 26 étant destinées à coopérer par encliquetage élastique avec des moyens complémentaires du connecteur 24.The adapter 26 is fixed to the connector 24 by means of the protuberances 60 which form means for fixing the adapter to the connector and which can furthermore form means for pivoting the adapter with respect to the connector. The fastening means are of the elastic snap-fastening type, the protuberances 60 of the adapter 26 being intended to cooperate by elastic snap-fastening with complementary means of the connector 24.

Le connecteur 24, mieux visible aux figures 3 et 4, est agencé pour être rendu solidaire, par exemple par sertissage, du balai d'essuyage 12. Le connecteur 24 assure une liaison mécanique dite complète avec le balai d'essuyage 12, en ce sens qu'il n'existe pas de degré de liberté. Le connecteur 24 peut également assurer une fonction de transport et de distribution d'un liquide de lavage du pare-brise du véhicule.The connector 24, better visible to Figures 3 and 4 , is arranged to be secured, for example by crimping, the wiper blade 12. The connector 24 provides a so-called mechanical connection complete with the wiper blade 12, in that there is no degree of freedom. The connector 24 can also provide a function for transporting and dispensing a washing liquid from the windshield of the vehicle.

Le connecteur 24 comprend une embase 70 qui s'étend longitudinalement et transversalement. Cette embase 70 comprend une zone de solidarisation 72 sur le balai d'essuyage 12, et plus particulièrement sur au moins une vertèbre 74 de ce balai d'essuyage. Cette zone de solidarisation 72 prend par exemple la forme d'une saignée ménagée dans l'embase 70, cette saignée étant bordée par deux crochets aptes à venir en prise sur le balai d'essuyage.The connector 24 comprises a base 70 which extends longitudinally and transversely. This base 70 comprises a securing zone 72 on the wiper blade 12, and more particularly on at least one vertebra 74 of this wiper blade. This securing zone 72 takes for example the form of a groove formed in the base 70, this groove being bordered by two hooks adapted to engage on the wiper blade.

Dans l'exemple représenté, le balai d'essuyage 12 comprend deux vertèbres 74 parallèles et coplanaires qui sont espacées l'une de l'autre pour définir un espace de logement de la lame d'essuyage 18 ou du corps 16 du balai d'essuyage. Chaque vertèbre comprend un bord longitudinal, opposé à la lame 18, qui est reçu dans la saignée du connecteur 24.In the example shown, the wiper blade 12 comprises two parallel and coplanar vertebrae 74 which are spaced from each other to define a housing space of the wiper blade 18 or the body 16 of the wiper blade. wiping. Each vertebra comprises a longitudinal edge, opposite the blade 18, which is received in the groove of the connector 24.

L'embase 70 est surmontée d'un flanc 76, par exemple, issu de matière avec l'embase. Ce flanc 76 présente une dimension transversale inférieure à celle de l'embase et une dimension longitudinale sensiblement égale à celle de l'embase. Le flanc 76 est par exemple centré sur l'embase 70, selon l'axe de pivotement Y. Le flanc 4 peut présenter une pluralité de nervures 78 qui assurent un renforcement mécanique du flanc.The base 70 is surmounted by a flank 76, for example, made of material with the base. This flank 76 has a transverse dimension less than that of the base and a longitudinal dimension substantially equal to that of the base. The flank 76 is for example centered on the base 70, along the pivot axis Y. The flank 4 may have a plurality of ribs 78 which provide a mechanical reinforcement of the sidewall.

Le connecteur 24 et l'adaptateur 26 sont reliés mécaniquement par une liaison pivot. En ce qui concerne le connecteur 24, cette liaison pivot est mise en oeuvre par une cavité 80 réalisée dans le flanc 76. Cette cavité 80 s'étend selon l'axe de pivotement Y et présente une section circulaire. Elle traverse le flanc 76. En d'autres termes, la cavité 80 a un axe central centré sur l'axe de pivotement Y.The connector 24 and the adapter 26 are mechanically connected by a pivot connection. As regards the connector 24, this pivot connection is implemented by a cavity 80 made in the sidewall 76. This cavity 80 extends along the pivot axis Y and has a circular section. It traverses the flank 76. In other words, the cavity 80 has a central axis centered on the pivot axis Y.

Le connecteur 24 décrit ci-dessus est avantageusement unitaire, c'est-à-dire constitué par une même matière synthétique. Ce connecteur peut ainsi être fabriqué au cours d'une unique opération de moulage, notamment par injection.The connector 24 described above is advantageously unitary, that is to say constituted by the same synthetic material. This connector can thus be manufactured during a single molding operation, in particular by injection.

L'adaptateur 26 est monté sur le connecteur 24 par encliquetage élastique de ses protubérances 60 dans la cavité 80 du connecteur. Les rampes 62 des protubérances 60 de l'adaptateur 26 coopèrent avec le connecteur pour faciliter ce montage. De son côté, le connecteur comprend également des moyens facilitant une insertion des protubérances 60 de l'adaptateur 26 dans sa cavité 10.The adapter 26 is mounted on the connector 24 by elastic snapping of its protuberances 60 in the cavity 80 of the connector. The ramps 62 of the protuberances 60 of the adapter 26 cooperate with the connector to facilitate this mounting. For its part, the connector also comprises means facilitating insertion of the protuberances 60 of the adapter 26 into its cavity 10.

Ces moyens sont ici aménagés sur le flanc 76 du connecteur 24. Il s'agit ici de rainures 82 ménagées dans les faces latérales délimitant le flanc 76, et au droit de laquelle la cavité 80 se termine. On comprend ici que chaque rainure 82 et la cavité 80 sont en intersection l'une avec l'autre, la rainure 82 s'étendant ainsi depuis une arête 84 du flanc 76 jusqu'au trou formant la cavité 80. Au droit de chaque rainure 82, le flanc 76 présente une épaisseur E1 inférieure à une épaisseur E2 d'une portion du flanc 76 bordant ladite rainure 82. Ces épaisseurs E1, E2 sont mesurées selon une direction parallèle à l'axe de pivotement Y. Ainsi formée, cette rainure 82 est délimitée par un fond 82a et par deux tranches 82b qui relient le fond 82a à la face latérale correspondant du flanc.These means are here arranged on the flank 76 of the connector 24. This is grooves 82 formed in the side faces defining the sidewall 76, and the right of which the cavity 80 ends. It will be understood that each groove 82 and the cavity 80 are in intersection with each other, the groove 82 thus extending from an edge 84 of the sidewall 76 to the hole forming the cavity 80. At the right of each groove 82, the flank 76 has a thickness E1 less than a thickness E2 of a portion of the flank 76 bordering said groove 82. These thicknesses E1, E2 are measured in a direction parallel to the pivot axis Y. Thus formed, this groove 82 is delimited by a bottom 82a and by two slices 82b which connect the bottom 82a to the corresponding side face of the sidewall.

Les fonds 82a des rainures 82 sont parallèles ou inclinés l'un par rapport à l'autre. Dans ce dernier cas, ils sont inclinés de sorte que leurs extrémités supérieures, situées du côté opposé à la cavité 80, soient plus proches que ne le sont leurs extrémités inférieures.The bottoms 82a of the grooves 82 are parallel or inclined with respect to each other. In the latter case, they are inclined so that their upper ends, located on the opposite side to the cavity 80, are closer than their lower ends.

L'assemblage de l'adaptateur 26 sur le connecteur 24 est réalisé uniquement par une translation verticale selon un axe perpendiculaire à la paroi supérieure 44 de l'adaptateur. Lors de cette translation, les protubérances 60 de l'adaptateur 26 s'engagent dans les rainures 82 du connecteur et coopèrent avec leurs tranches 82b pour centrer l'adaptateur sur le connecteur. Les rampes 62 ont des surfaces de guidage qui coopèrent par glissement avec les fonds 82a des rainures. Pour cela, la distance L précitée est de préférence supérieure à l'épaisseur E1. Par ailleurs, la distance inter protubérances 60, mesurée le long de l'axe de pivotement Y, est inférieure à la largeur de la cavité 80 ainsi que l'épaisseur E2.The assembly of the adapter 26 on the connector 24 is made only by a vertical translation along an axis perpendicular to the upper wall 44 of the adapter. During this translation, the protuberances 60 of the adapter 26 engage in the grooves 82 of the connector and cooperate with their slices 82b to center the adapter on the connector. The ramps 62 have guide surfaces that slide cooperatively with the bottoms 82a of the grooves. For this, the distance L above is preferably greater than the thickness E1. Furthermore, the distance between protuberances 60, measured along the pivot axis Y, is less than the width of the cavity 80 and the thickness E2.

Lors de l'insertion des protubérances 60 dans les rainures 82, les rampes 62 prennent appui sur les fonds des rainures et la translation vers le bas de l'adaptateur est poursuivie de sorte que les parois latérales 42a, 42 de l'adaptateur soient contraintes de se déformer en s'écartant l'une de l'autre du fait du glissement des rampes sur les fonds des rainures. Cette opération est poursuivie jusqu'à ce que les protubérances 60 s'engagent par encliquetage ou retour élastique dans la cavité 80 du connecteur. L'adaptateur est alors fixé au connecteur et peut en outre pivoté sur lui autour de l'axe de pivotement Y, par coopération de ses protubérances avec la surface cylindrique interne 80a de la cavité. La cavité 80 a un diamètre interne sensiblement égal ou légèrement supérieur à celui des protubérances 60. On obtient alors le montage représenté en figure 9.When the protuberances 60 are inserted into the grooves 82, the ramps 62 rest on the bottoms of the grooves and the downward translation of the adapter is continued so that the side walls 42a, 42 of the adapter are constrained. to deform by moving away from each other due to the slippage of the ramps on the bottoms of the grooves. This operation is continued until the protuberances 60 engage snap or elastic return into the cavity 80 of the connector. The adapter is then attached to the connector and may further pivoted about it about the pivot axis Y, by cooperation of its protuberances with the inner cylindrical surface 80a of the cavity. The cavity 80 has an internal diameter substantially equal to or slightly greater than that of the protuberances 60. The assembly shown in FIG. figure 9 .

Comme évoqué précédemment, l'adaptateur 26 est du type universel car il est apte à être fixé à plusieurs types de bras, que ce soit des bras à pièce terminale ou sans pièce terminale.As mentioned above, the adapter 26 is of the universal type because it is adapted to be attached to several types of arms, whether end piece arm or without end piece.

Les figures 10 à 20 montrent plusieurs types de bras pouvant être équipés de l'adaptateur 26 selon l'invention.The Figures 10 to 20 show several types of arms that can be equipped with the adapter 26 according to the invention.

On se réfère d'abord aux figures 10 et 11 qui représentent respectivement deux pièces terminales 28, 28' de bras d'entraînement différents.We first refer to Figures 10 and 11 which respectively represent two end pieces 28, 28 'of different drive arms.

Chaque pièce terminale 28, 28' comprend deux jambes latérales 32a, 32b dont les bords longitudinaux supérieurs sont reliés entre eux par une paroi transversale supérieure 34. Les jambes 32a, 32b et la paroi 34 délimitent entre elles un espace de logement de l'adaptateur 26. Les jambes 32a, 32b peuvent comprendre au niveau de leurs bords longitudinaux inférieurs des moyens 36, tels que des crochets, de retenue de l'adaptateur 26 dans l'espace précité.Each end piece 28, 28 'comprises two lateral legs 32a, 32b whose upper longitudinal edges are interconnected by an upper transverse wall 34. The legs 32a, 32b and the wall 34 delimit between them a housing space of the adapter 26. The legs 32a, 32b may comprise at their lower longitudinal edges means 36, such as hooks, retaining the adapter 26 in the aforementioned space.

La paroi supérieure 34 comprend une ouverture 38, 38' traversante destinée à recevoir le bouton poussoir supérieur 27. En position de montage, le bouton poussoir 27 est logé dans cette ouverture 38 et peut traverser cette dernière de façon à être en saillie sur la face supérieure de la paroi 34. Le montage du bouton poussoir 27 dans l'ouverture 38 se fait par simple engagement ou emboîtement, de préférence par encliquetage élastique.The upper wall 34 comprises a through opening 38, 38 'intended to receive the upper push button 27. In the mounting position, the push button 27 is housed in this opening 38 and can pass through the latter so as to project on the face upper wall 34. The mounting of the push button 27 in the opening 38 is by simple engagement or interlocking, preferably by snap elastic.

Les parois latérales 32a, 32b peuvent comprendre chacune une encoche 40 de forme complémentaire d'un bouton poussoir latéral 27'. En position de montage, les boutons poussoirs latéraux 27' sont logés dans ces encoches 40 et peuvent les traverser de façon à être en saillie sur les faces externes des parois 32a, 32b. Le montage des boutons poussoirs 27" dans les encoches 40 se fait par simple engagement ou emboîtement, de préférence par encliquetage élastique.The side walls 32a, 32b may each comprise a notch 40 of complementary shape of a lateral push button 27 '. In the mounting position, the lateral push buttons 27 'are housed in these notches 40 and can pass through so as to project on the outer faces of the walls 32a, 32b. Mounting the push buttons 27 "in the notches 40 is by simple engagement or interlocking, preferably by snap elastic.

Les pièces terminales 28, 28' sont différentes. Elles ont globalement la même forme mais diffèrent les unes des autres notamment par des dimensions et par la forme et la taille de leurs ouvertures 38, 38' ou encoches 40.The end pieces 28, 28 'are different. They have generally the same shape but differ from each other in particular by size and the shape and size of their openings 38, 38 'or notches 40.

Les parois supérieures 34 des pièces terminales 28, 28' se prolongent vers l'extérieur pour former chacune une patte 41 à section longitudinale sensiblement en S, qui est configurée pour être engagée dans l'orifice 51 de l'adaptateur 26.The upper walls 34 of the end pieces 28, 28 'extend outwardly to each form a tab 41 of longitudinal section substantially S, which is configured to be engaged in the orifice 51 of the adapter 26.

Les pièces terminales 28, 28' ont sensiblement la même largeur externe. Par ailleurs, les nervures 54 des faces externes des parois latérales du corps de l'adaptateur 26 peuvent être espacées d'une paroi à l'autre d'une distance transversale sensiblement égale à la largeur interne de la pièce transversale 28, 28', de façon à ce que la pièce terminale soit calée en direction transversale par coopération de ses jambes avec les parois latérales du corps de l'adaptateur.The end pieces 28, 28 'have substantially the same external width. Furthermore, the ribs 54 of the outer faces of the side walls of the body of the adapter 26 may be spaced from one wall to the other by a transverse distance substantially equal to the internal width of the crosspiece 28, 28 ', so that the end piece is wedged in transverse direction by cooperation of its legs with the side walls of the body of the adapter.

On va maintenant décrire le montage de l'adaptateur 26 selon l'invention sur chacune des pièces terminales 28, 28'.We will now describe the mounting of the adapter 26 according to the invention on each of the end pieces 28, 28 '.

L'adaptateur 26 est engagé dans la pièce terminale 28, 28' en inclinant tout d'abord l'axe de l'adaptateur vis-à-vis de celui A de la pièce terminale 28 puis en engageant la patte 41 de la pièce terminale dans l'orifice 51 de l'adaptateur. Lors de cet engagement, les jambes de la pièce terminale commencent par glisser sur les moyens d'appui 54 de l'adaptateur. De plus, le bord d'extrémité avant de la paroi supérieure de la pièce terminale vient en appui sur la face 48b de la tête 46 de l'adaptateur. L'extrémité arrière de l'adaptateur est ensuite rapprochée de la pièce terminale jusqu'à ce que les boutons poussoirs latéraux 27' s'engagent par encliquetage élastique dans les encoches 40 de la pièce terminale 28, 28'. Les bords d'extrémité avant des jambes latérales 32a, 32b de la pièce terminale viennent en appui sur les faces 48a de la tête 46 de l'adaptateur. Les axes longitudinaux de l'adaptateur et de la pièce terminale 28 sont alors sensiblement parallèles.The adapter 26 is engaged in the end piece 28, 28 'by first tilting the axis of the adapter vis-à-vis the A of the end piece 28 and then engaging the tab 41 of the end piece in the hole 51 of the adapter. During this engagement, the legs of the end piece begin to slide on the support means 54 of the adapter. In addition, the front end edge of the upper wall of the end piece bears on the face 48b of the head 46 of the adapter. The rear end of the adapter is then brought closer to the end piece until the lateral push buttons 27 'engage by snap elastically in the notches 40 of the end piece 28, 28'. The front end edges of the lateral legs 32a, 32b of the end piece bear against the faces 48a of the head 46 of the adapter. The longitudinal axes of the adapter and the end piece 28 are then substantially parallel.

On se réfère maintenant aux figures 12 à 15, dans lesquelles l'adaptateur 26 est relié à un bras 14 du type bras tige, c'est-à-dire dépourvu de pièce terminale supplémentaire, par l'intermédiaire d'un premier organe de liaison 88.We now refer to Figures 12 to 15 , in which the adapter 26 is connected to an arm 14 of the rod-arm type, that is to say without additional end piece, via a first connecting member 88.

Cet organe de liaison 88 est monté sur l'adaptateur 26 et le recouvre intégralement dans l'exemple représenté. Il a une forme longitudinale et comprend un logement interne dans lequel est monté et retenu l'adaptateur. Il comprend à son extrémité arrière des encoches latérales destinées à recevoir par encliquetage élastiques les boutons poussoirs 27', respectivement.This connecting member 88 is mounted on the adapter 26 and covers it integrally in the example shown. It has a longitudinal shape and includes an inner housing in which is mounted and retained the adapter. It comprises at its rear end lateral notches intended to receive by snap elastic push buttons 27 ', respectively.

Des parois latérales 85, 86 de l'organe 88 comprennent sur leurs faces internes 87, 89 des moyens en saillie 100, 100a qui définissent des faces d'appui en direction transversale, et qui sont configurés pour coopérer avec les moyens d'appui en saillie 54, 54a de l'adaptateur 26.Side walls 85, 86 of the member 88 comprise on their inner faces 87, 89 projecting means 100, 100a which define bearing faces in the transverse direction, and which are configured to cooperate with the bearing means projection 54, 54a of the adapter 26.

Les moyens en saillie 100, 100a de l'organe 88 comprennent ici des bandes de matière 100, 100a en saillie sur les faces internes 87 et 89 des parois latérales 85, 86 de l'organe 88. Les bandes de matière ont une forme allongée et s'étendent longitudinalement entre les bords longitudinaux inférieurs et supérieurs de ces parois.The projecting means 100, 100a of the member 88 here comprise strips of material 100, 100a projecting on the inner faces 87 and 89 of the side walls 85, 86 of the member 88. The strips of material have an elongated shape and extend longitudinally between the lower and upper longitudinal edges of these walls.

Les bandes de matière 100, 100a définissent des surfaces d'appui sensiblement parallèles. Ces surfaces d'appui sont ici sensiblement parallèles aux faces internes 87, 89 des parois latérales ainsi qu'à l'axe longitudinal A de l'organe 88.The strips of material 100, 100a define substantially parallel bearing surfaces. These bearing surfaces here are substantially parallel to the inner faces 87, 89 of the side walls and to the longitudinal axis A of the member 88.

Les bandes de matière 100, 100a sont espacées en direction longitudinale les unes des autres et réparties sur les parois latérales 85, 86 dans la même direction. Dans l'exemple représenté, chaque paroi latérale comprend trois desdites bandes de matière. Les bandes de matière de l'une des parois latérales sont symétriques par rapport aux bandes de matière de l'autre des parois latérales, par rapport à un plan longitudinal médian de l'organe perpendiculaire à sa paroi supérieure.The strips of material 100, 100a are spaced longitudinally from each other and distributed on the side walls 85, 86 in the same direction. In the example shown, each side wall comprises three of said strips of material. The strips of material of one of the side walls are symmetrical with respect to the strips of material of the other of the side walls, with respect to a median longitudinal plane of the member perpendicular to its upper wall.

Les bandes de matière ont sensiblement toutes la même épaisseur ou dimension en direction transversale, mesurée selon l'axe de pivotement Y. Les bandes de matière médianes 100a ont une largeur ou dimension en direction longitudinale, mesurée selon la direction longitudinale A inférieure à celle des autres bandes de matière.The strips of material have substantially all the same thickness or dimension in the transverse direction, measured along the pivot axis Y. The median material strips 100a have a width or dimension in the longitudinal direction, measured along the longitudinal direction A less than that of the other strips of material.
